they are harder to make though. the 'dry' type that expand a bit faster also have less density making even a small hole fit well. with the slow expanding materials, a small hole will make the remaining material very dense and even hurt small ear canals. i have to punch quite a bit out with my small hobby holepunch

I've been considering this too, and maybe I'll give it a shot since I have a fistful of earplugs from work that I don't really need anymore.. But I'm kinda liking the ones that came with my Atrios, they retain the shape so I don't have to squeeze them every time and then hold them in while they enlarge.

To me, that is the biggest problem with any foam tips. It's especially relevant if you're constantly having to remove your earphones (like if someone needs to speak with you at work, or the phone rings). Those few seconds for foam to expand don't seem like much, but it can become an issue.

I problem for me as well. But what to do this is life. Usually I use PTH for Shures but not much since it's spoiling SQ a bit.
